Plain English summary of protocol

Background and study aims:
Type 2 diabetes mellitus (T2DM) is a disease with high mortality rates. It is the most common endocrine disorder worldwide. People with diabetes are at increased risk of cardiovascular diseases. The current treatment includes diet control, exercise, and use of anti-diabetic meditations. However, recent evidence suggests surgery can reduce the symptoms of T2DM, especially in morbidly obese patients. The aim of our study is to evaluate the effectiveness and safety Laparoscopic Roux-en-Y gastric Bypass (LRYGB) surgery in non obeseT2DM patients.

Who can participate?
Either male or female patients aged 18 - 65 years, with a Body Mass Index (BMI) of less than 27 kg/m2. Participants should also be diagnosed with T2DM for at least 6 months.

What does the study involve?
Laparoscopic Roux-en-Y gastric Bypass (LRYGB) surgery.

What are the possible benefits and risks of participating?
Patients may experience reduced symptoms of T2DM, however there is the risk that there maybe complications from the surgery.

Where is the study run from?
EDa Hospital, Taiwan

When is the study starting and how long is it expected to run for?
The study started in June 2009 and ended in May 2011.
